Mode-Locking and Q-Switching in Holmium Doped Fiber Laser Using Topological Insulator (Sb₂Te₃) as Saturable Absorber

Abstract: This work demonstrates mode-locking and Q-switching in a holmium-doped fiber laser (HDFL) using topological insulator (TI) antimony telluride (Sb2Te3) as the saturable absorber (SA). The TI ...
